We cruised out of New Orleans this year on the Conquest. Mardi Gras was in full bloom. No there was nothing special on the boat other than some people wearing beads. It was something to see. I would book my room now. If you wait you may not get one. We had a heck of a time getting a room 8 months prior to the cruise.
DDF, Obviously you know Mardi Gras 2006 is February 28, so ......
I have not heard of any ship that does anything special. I'm surprised that the ships leaving N.O. the few weeks prior to Mardi Gras DON'T do anything special. It's the perfect opportunity to have a little MG party, or at least the dining room waiters could do 'the second line' (traditional MG conga line dance) around the tables. I'm from N.O., so it's such a special time for me.....just wish it were carried through on the ships.
With the parades in full swing while you'll be there, hope you get to take in a few.
